Spanning two six-month seasons from April 1964 to October 1965, the fair was full of space-age futurism, newfangled technologies, and more than its share of controversy.

The 1964-1965 fair was the third major World’s Fair to be held in New York City. The theme of the '64 fair was Peace Through Understanding and was symbolized by a 12-story stainless-steel model of the Earth called the Unisphere. It was built by U.S. Steel.
